-
Technical Specifications:
-
Input Voltage: 75V to 149V AC/DC (Auto-ranging).
-
Output Voltages: Regulated +5V, +/-15V DC for logic and analog circuits.
-
Power Rating: Sufficient to drive control circuits and cooling fans.
-
-
Structural Features:
-
Components: Populated with 7 transformers, multiple relays, rectifiers, and filtering capacitors.
-
Connectors: Features 18 plug-in connectors and 9 pin headers for interfacing with other Mark V boards and field devices.
-
Indicators: Includes one neon lamp (for AC power presence) and two LEDs (for +5V and +15V status).
-
-
Working Principle: The board takes the high-voltage AC input, steps it down via transformers, rectifies it to DC, and then regulates it to precise voltage levels. It also conditions feedback signals (like motor speed or current) before sending them to the main controller for closed-loop control.
-
Usage Notes: Due to the presence of high voltages and large capacitors, the board must be allowed to discharge for several minutes after power removal before handling. Proper fusing is essential to protect the circuitry.
